Molar and molecular weight of HCsO

• Molecular formula: HCsO or CsOH
• Relative molecular weight of HCsO: 149.9127919
• Molar mass of HCsO: 149.9127919 g/mol (0.14991 kg/mol)

Calculation of the relative molecular and molar mass of HCsO

• Mr[HCsO] = Ar[H] + Ar[Cs] + Ar[O] = 1.00794 + 132.9054519 + 15.9994 = 149.9127919
• Molar mass (kg/mol) = Mr[HCsO] : 1000 = 149.9127919 : 1000 = 0.14991 kg/mol

HCsO: percent composition by element

• Hydrogen (H) = 1.00794 : 149.9127919 * 100 = 0.672 %
• Cesium (Cs) = 132.9054519 : 149.9127919 * 100 = 88.655 %
• Oxygen (O) = 15.9994 : 149.9127919 * 100 = 10.672 %
